Abstract
A decision sometimes needs to consider many aspects and to be judged by many people. Presenting a case of finding a suitable location for a new school this research proposes seven factors which its emphasis will be differently sorted by various people perspective. Each factor comes in a form of a multi-polygon layer that valued from 0 to 9, representing the suitability value of the certain aspect in the whole city area. The Public and some expert will judge by using the pair-wise comparison of those aspects. This research will provide web GIS application that will use by the public and the expert in this justification process and analyzing the result.

We must own the server by ourselves or we have to pay more hosting service that includes Mapserver or Geoserver, a service that not exist in the common hosting provider. Another way that can be hosted in common hosting service is to store the map in a common database like MySQL or Postgres and using Javascript based tool for showing the map in client’s browser
In the MCDA process, the map will be simplified to 20% of the real size to supply fast respond to the user
Summary
Surabaya is an expanded old city and grows up reaching its form like today. Starting in the colonial era, Surabaya citizens lived in the district area. Surabaya populated area has expanded to the south, east, and west area. This expanded population is not accompanied by new public school development, especially the high school level. It can be seen that the city has a lack of public high schools. It shows that there exists a scarcity of educational institutions at the higher levels, making it common for students to travel much longer distances as they move to higher levels of study [6]
